It looks like you're already on your way there. With the exception of "This is text inside the editor." which is not inside any tags. And I see you have namespaces, not exactly "beginner" level.

What you are doing is writing an XML file (eXtensible ML) which basically means that as long as you follow the rules of XML, you can do just about anything. Then use XSLT to change it to (X)HTML (or other formats).

Note* You can use CSS directly on XML without changing it to XHTML if you want to.

I got this <sn:editor> example tag from Bebo website, it allow user to develop own application.

On Facebook, they use FBML (Facebook Markup Language). They have written apache module in C++ for FBML instead of using XSLT.

However, I can not see anything on bebo website using XSLT. They probably did the same what Facebook did.
